  • a shoulder seat 23 is formed so that the distance between the surfaces defining the shoulder seat 23 increases in the widthwise direction D 3 toward the open end of the socket 21 .
  • the ends of the shoulder seat 23 farther from the open end of the socket 21 define shoulder abutment edges 24 .
  • the shoulder abutment edges 24 abut against the inclined surfaces 33 of the shoulder 36 in a manner that the shoulder abutment edges 24 are mated with the inclined surfaces 33 under pressure. That is, the inclined surfaces 33 of the shoulder 36 are press-fitted to the shoulder abutment edges 24 of the shoulder seat 23 .
  • the press-fitting absorbs dimensional errors of the key plate 30 in the widthwise direction D 3 .
  • the socket 21 includes guides 25 .
  • Each guide 25 is defined by a slanted surface linearly extending between the two walls of the socket 21 that face toward the corresponding guide abutment edge 35 in a state in which the shank 31 is inserted into the socket 21 .
  • the guides 25 guide the guide abutment edges 35 of the shank 31 during insertion of the key plate 30 into the socket 21 . Further, the guides 25 abut against the guide abutment edges 35 in a manner that the guides 25 are mated with the guide abutment edges 35 under pressure. That is, the guide abutment edges 35 are press-fitted to the guides 25 .
  • the guides 25 function as a movement restriction portion for restricting movement of the key plate 30 in directions perpendicular to the insertion direction D 1 .
  • the guides 25 restrict movement of the guides 25 in the thicknesswise direction D 2 and the widthwise direction D 3 .
  • the press-fitting of the guide abutment edges 35 to the guides 25 absorbs errors in the cross-sectional dimensions of the key plate 30 . That is, the press-fitting absorbs dimensional errors in the thicknesswise direction D 2 and the widthwise direction D 3 .
  • the guides 25 are each formed in the socket 21 to extend in the insertion direction D 1 from the wall that comes into contact with the distal end of the key plate 30 to the middle part of the socket 21 .
  • the guides 25 are formed at corners located between the surface of the socket 21 extending in the widthwise direction D 3 and facing toward the guide abutment edges 35 and each of the two surfaces extending from that surface in the thicknesswise direction D 2 .
  • the guides 25 extends linearly at an angle of approximately 45° with respect to the thicknesswise direction D 2 and the widthwise direction D 3 .
  • a tapered surface 26 extends diagonally toward the opening 22 from each guide 25 .
  • the tapered surfaces 26 contact and guide the guide abutment edges 35 of the key plate 30 .
  • the guides 25 press the key plate 30 against the wall of the socket 21 that is located on the opposite side of the guide abutment edges 35 . This positions and fixes the key plate 30 in the socket 21 .
  • holes 27 extends through the grip 20 in the widthwise direction D 3 .
  • a grip recess 28 is formed in the grip 20 extending in the widthwise direction D 3 .
  • the holes 27 and the grip recess 28 are located between the shoulder seat 23 and the guides 25 in correspondence with the plate recess 34 of the key plate 30 .
  • a pin 29 FIG. 1A
  • the pin 29 which is inserted through the grip 20 and retained in the plate recess 34 , prevents the key plate 30 from moving out of the socket 21 in the insertion direction D 1 and holds the key plate 30 in the grip 20 .
  • the guides 25 of the grip 20 restrict movement of the distal part of the shank 31 that is inserted into the socket 21 . Further, the inclined surfaces 33 of the shoulder 36 restrict pivoting of the key plate 30 about the distal part of the shank 31 . Thus, movement of the shank 31 of the key plate 30 in the thicknesswise direction D 2 and the widthwise direction is restricted.
  • the preferred embodiment has the advantages described below.
  • the guides 25 of the grip 20 restrict movement of the key plate 30 in directions perpendicular to the insertion direction D 1 (i.e., the thicknesswise direction D 2 and the widthwise direction D 3 ). Further, the inclined surfaces 33 of the key plate 30 restrict pivoting of the key plate 30 about the distal part of the shank 31 . Thus, movement of the shank 31 of the key plate 30 when inserted into the grip 20 is restricted. This ensures positioning of key plate 30 in the socket 21 and prevents the key plate 30 from becoming loose.
  • the guides 25 guide the guide abutment edges 35 of the shank 31 in the insertion direction D 1 of the key plate 30 .
  • the key plate 30 is smoothly inserted into the socket 21 .
  • the guide abutment edges 35 of the key plate 30 are mated with the guides 25 under pressure (press-fitted) in correspondence with the cross-sectional dimensions of the key plate 30 . This absorbs errors in the cross-sectional dimensions (dimensions in the thicknesswise direction D 2 and the widthwise direction D 3 ) of the key plate 30 .
  • the tapered surface 26 extends diagonally toward the opening 22 of the socket 21 from each guide 25 .
  • each tapered surface 26 guides the distal part of the key plate 30 .
  • the key plate 30 is smoothly inserted into the socket 21 .
  • the tapered surfaces 26 are formed extending from the guides 25 toward the opening 22 .
  • the tapered surfaces 26 are not necessarily required.
  • the guides 25 are arranged on opposite sides of the wall extending in the widthwise direction D 3 .
  • the guides 25 may take other forms as long as movement of the key plate 30 in directions perpendicular to the insertion direction D 1 of the shank 31 is restricted.
  • the guides 25 may be arranged on opposite sides of a wall extending in the thicknesswise direction D 2 .
  • the key plate 30 includes the inclined surfaces 33 , which are linear such that the distance between the inclined surfaces 33 gradually increase in the widthwise direction D 3 toward the blade 32 .
  • the inclined surfaces 33 may have other forms as long as pivoting of the key plate 30 about the distal part of the shank 31 is restricted.
  • the shoulder abutment edges 24 of the grip 20 that abut against the inclined surfaces 33 of the key plate 30 may take any form as long the shoulder abutment edges 24 abut against the inclined surfaces 33 and restrict pivoting of the key plate 30 about the distal part of the shank 31 .
  • the shoulder abutment edges 24 be located as far as possible from the distal part of the shank 31 . This would space the shoulder abutment edges 24 from the pivoting center of the key plate 30 and position and fix the key plate 30 in the socket 21 in an optimal manner.
  • the grip 20 and the key plate 30 are made of metal.
  • the grip 20 and the key plate 30 do not have to be made of metal and may be made of, for example, resin.
